Print out the checklist. Write in 1, 2 or 3 very specific habits (i.e. drink 2 cups of water before breakfast, eat a vegetable at every meal, eat evening snack using table-plate-chair) across the top of the checklist. Fill in the dates for the next 30 days. Each day, give yourself a checkmark (or a smiley face) for each habit you complete. Tracking habits is even better than a food log!
